MIP consequences with Previous offences in another State.?

Iam a freshman at LSU. On Halloween i received an MIP entering tiger stadium. I tried to sneak in a flask of alcohol and got caught. I was issued the MIP from the officer and went on my way. Im originally from NC and i have a DUI on my record in that state. My question is, how do i need to take care of this ticket? How much is it/what are the consequences, and will the DA be able to see my previous record and my punishment will be harsher than normal? And will LSU do anything to me like kick me out of college?
